ARTHUR WATHEY, OF CLEVELAND, OHIO STOKER CYLINDER.

Application filed June 3,

l To all whom Lt-may concern Be it known that I. ARTHUR WATHEY, acitizen of the United States, residing at Cleveland, in the county ofCuyahoga and State of Chio` have invented certain new and usefulImprovements in Stoker Cylinders. of which the following is a full,clear,

and exact specification. r

This invention relates tomechanical stokers for boiler furnaces, and hasfor its object to provide an improved form of `cylinder for suchstokers.

The cylinders, through which the rams or pushers work for feeding fuelinto the furnace, have heretofore been made of solid or integralcastings` und when holes are worn through the bottoms thereof, which isbound to occur after a certain period of use, it has been necessary totake down the worn re torts and replace them with new ones atconsiderable expense. Not only does the cost of the new completecylinders' and the time of workmen involve a great outlay of money, butthe furnace must be put out' of use fora considerable length of timewhile the repairs are being made.

It is the aim of the present invention to provide a cylinder for stokerswhich does not have to be entirely replaced when its bottom ,wears out,vso that much of the expenseand time required heretofore for making`repairs is saved and the main portion of cylinder utilized for a muchlonger period than before:

The invention will be first hereinafter described in connectionv withthe accompanying drawings, which constitute part of this specification,and then more specically defined in lthe claims at theend of thedescription. 1

In the accompanying drawings, wherein similar reference characters areused to designate corresponding parts throughout the several viewsconstructed substantially in accordance with the resent invention. 1

Figure 2 is a right hand end elevation of the same.

Figur'eB is a left hand end elevation of the cylinder.

Figure 4 is a longitudinal vertical section on the line IV-IV of Figure2.

Figure 5 is a transverse vertical section on the line .Vl-V of Figure 1looking towards the right, and

Figure 1 is `a side elevation of a cylinder 1922. Serial No. 565,638.

Figure 6. is a detailed plan view of the removable bottom for thecylinder.

The cylinder 1 is'preferably made in accordance with the presentpractice except that instead of having a solid or integral bottom thebottom 2 is here made as a separate casting which may be adjustedvertically to take up wear and replaced by a new bottom when it becomesworn through. r In use, the left hand end of the cylinder in Figure 1 isapplied to the furnacey (not` shown) while the right hand end, having ithe hopper 3, is intended to have the ram or pusher (not shown)introduced therein.

The adjustable and removable bottom.y 2 may extend substantiallythroughout the path of the ram or pusher, and as shown best in Figure4;, need not constitute the entire bottom of the cylinder. Said bottom 2is preferably formed of chilled steel, at least its upper ram engagingsurface is chilled, in order to render the same more durable. Said uppersurface is channeled to conform der, and preferably has longitudinalside members 4: and transverse truss members 5,

said side members fitting within corresponding side members 6 extending;along themargins of the opening 7 in the bottom of the cylinder in whichsaid removable bottom 2 is arranged, see Figure 5.

The bottom 2 is held in place by bolts 8 engaging outwardly extendingflanges 9 and 10 respectively on' the side memberst and 6. Between saidflanges a plurality-of shims or liners 11, preferably one-eighth of aninch in thickness, are placed in order that as the upper surface of thevbottom 2 wears down said shims or liners may be removed one at a timeto compensate for said wear.

When the last of the shims or liners has been removed on each s ide andthe bottom wears entirely through, it may be quickly taken out throughthe opening 7 in the cylinde/r upon removing the bolts 8 without movingthe main upper section of the cylinder. or disturbingthe boiler front,coal chute or any other part of the Stoker. -`Whereas it takes about aweek to remove six retorts or cylinders and replace them with entirely-new ones according to the old practice, `the bottomsmay be renewed whenthe 'present invention is used in about three hours. It will thus beseen that this invention means aigreat saving in time and expense anddoes away with the necessity of anu-a interru' the um `ofboilors forlong repairs` to the stoker cylinders.
